Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of the connection preparation in the mac80211 module. This failure results in the site not...

PT-2026-44545

AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. Prior to 1.13.0, the AnythingLLM agent filesystem copy tool validates only the top-level source and destination paths. The recursive copy helper then descends into child...

CVE-2026-45961

A flaw was found in the Linux kernel's GFS2 filesystem. When a GFS2 filesystem transitions to read-write mode, specific error handling paths within the gfs2fillsuper function fail to properly deallocate memory. This can lead to memory leaks of kernel thread objects and quota bitmap buffers. Over...

CVE-2026-45985

A flaw was found in the Linux kernel's ext4 filesystem. When allocating blocks for direct I/O DIO and writeback, an incorrect flag handling during extent splitting could lead to a mismatch between the on-disk extent status and the extent status tree. This issue, particularly when a temporary erro...

CVE-2026-45991

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. A remote attacker could exploit this vulnerability by tricking a user into mounting a specially crafted UDF image containing repeated partition descriptors. This could lead to a heap out-of-bounds write, potentially...

CVE-2026-46002

A flaw was found in the Linux kernel's ext2 filesystem. A local attacker could create a specially crafted filesystem image with malformed inodes index nodes that, when mounted, would not be properly rejected by the ext2iget function. This could lead to a kernel warning and potentially a system...

CVE-2026-46005

A flaw was found in the Linux kernel's xfs filesystem. This resource leak occurs in the xfsallocbuftarg function's error path, where a DAX Direct Access device reference is not properly dropped. An attacker could potentially exploit this flaw to cause resource exhaustion, leading to a Denial of...

CVE-2026-44712

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, a crafted UUID such as $id/tmp/rce in the config causes root RCE when pamusb-conf --reset-pads is run. A USB device with a crafted filesystem UUID some controllers allow this can inject the payload a...

CVE-2026-44712 pam_usb: Shell injection via device UUID and username in pamusb-conf and pamusb-agent

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, a crafted UUID such as $id/tmp/rce in the config causes root RCE when pamusb-conf --reset-pads is run. A USB device with a crafted filesystem UUID some controllers allow this can inject the payload a...

CVE-2026-46046

A flaw was found in the Linux kernel's ext4 filesystem. A reference count refcount leak occurs in the ext4xattrinodedecrefall function. This issue arises because the iloc.bh buffer head, acquired by ext4getinodeloc, is not properly released with brelse. This can lead to resource exhaustion or...

CVE-2026-46052

A flaw was found in the Linux kernel's Ceph filesystem. A local user or process interacting with the Ceph filesystem could trigger a dcache hash corruption when a negative dentry is incorrectly re-added to the dcache hash while it is already present. This can cause the system to experience an RCU...

Pimcore has Unsafe PHP Deserialization in Multiple Locations Without allowed_classes Restriction

GitHub Security Advisory Draft — GM-374 Summary Multiple locations in Pimcore v11 call PHP's unserialize on data from database columns and filesystem files without the allowedclasses restriction, enabling object injection if an attacker can control the serialized data source. Severity CVSS 3.1: 8...

In the Linux kernel, the following vulnerability has been resolved: ext4: don't cache extent during splitting extent Caching extents during the splitting process is risky, as it may result in stale extents remaining in the status tree. Moreover, in most cases, the corresponding extent block entri...
